fimbriate or crenulate scales as there are lobes and alternate with them, or these 
sometimes obsolete. Stamens as many as the corolla-lobes and alternate with 
them, inserted in the throat or sinuses above the scales, short-exserted or included ; 
filaments short or slender; anthers short, ovate or oval, obtuse, 2-celled, the sacs 
longitudinally dehiscent. Ovary globose to oblong, 2-celled ; ovules 2 in each

i. CUSCUTA [Tourn.] L. Sp. PL 124. 1753. 

Characters of the family. The filiform twining stems are parasitic on herbs and shrubs 
by numerous minute suckers. The seeds germinate in the soil and the plantlet attaches itself 
to its host, its root and lower portion soon perishing. The subsequent nutrition of the 
parasite is apparently wholly through its suckers. [Name from the Arabic.]

berulent than L. virginiciis; stems rather slender, 
simple or sparingly branched, 4'-2 tall, rather 
acutely angled, tuberous at the base, the stolons 
rarely tuber-bearing. Leaves oblong or oblong- 
lanceolate, acute or acuminate at the apex, ser- 
rate, f'-3f long, sessile or nearly so; calyx-teeth 
4 or 5, triangular, ovate or ovate-oblong, rather 
obtuse; corolla about il" long, less than twice as

often coarsely-toothed, longer-petioled and larger

THISTLE FAMILY. 

Herbs, rarely shrubs (some tropical forms trees), with watery or resinous 
(rarely milky) sap, and opposite alternate or basal exstipulate leaves. Flowers 
perfect, pistillate, or neutral, or sometimes monoecious or dioecious, borne on a 
common receptacle, forming heads, subtended by an involucre of few to many bracts 
arranged in one or more series. Receptacle naked, or with chaffy scales subtend- 
ing the flowers, smooth, or variously pitted or honeycombed. Calyx-tube com- 
pletely adnate to the ovary, the limb (pappus) of bristles, awns, teeth, scales, or 
crown-like, or cup-like, or wanting. Corolla tubular, usually 5-lobed or 5-cleft, the 
lobes valvate, or that of the marginal flowers of the head expanded into a ligule 
(ray) ; when the ray-flowers are absent the head is said to be discoid ; when present, 
radiate ; the tubular flowers form the disk. Stamens usually 5, borne on the corolla 
and alternate with its lobes, their anthers united into a tube (syngenesious), often 
appendaged at the apex, sometimes sagittate or tailed at the base ; pollen-grains 
globose, often rough or prickly. Ovary i-celled; ovule I, anatropous; style of 
fertile flowers 2-cleft, its branches variously appendaged, or unappendaged ; stigmas 
marginal ; style of sterile flowers commonly undivided. Fruit an achene. Seed 
erect; endosperm none; embryo straight; hypocotyl inferior.

shorter, usually woolly. Receptacle convex, or nearly flat, foveolate, not chaffy. Staminate 
flowers with a truncate or minutely dentate corolla, usually undivided style and scanty pappus 
of club-shaped smooth or minutely barbed bristles. Pistillate or perfect flowers with tubular 
mostly 5-toothed corollas, 2-cleft style, and copious pappus of capillary naked bristles, slightly 
united at the base, the style often crimson. Achenes oblong, terete, or slightly compressed.

About 50 species, natives of the north temperate zone and southern South America. In addi-

fertile and sterile plants are usually quite distinct, and the sterile plants of some species are much 
less abundant than the pistillate. Perfect achenes are, however, abundant, parthenogenesis being 
a known feature of this genus. Type species: Antennaria dioica (L.) Gaertn.
